Pipeline mixer

The invention relates to the technical field of chemical engineering and environmental protection and in particular to a pipeline mixer. The pipeline mixer has a fluid pipe. A branch pipe communicating with the fluid pipe is arranged on one end of the fluid pipe as a diluting pipe, at least two baffle plates are arranged in the fluid pipe, and the baffle plates are arranged alternately in an equally spaced manner by facing the other end of the fluid pipe. The pipeline mixer provided by the invention is simple in structure and low in cost, guarantees that two types of gas are uniformly mixed in the pipeline, and is suitable for being popularized and applied on a large scale. 本发明涉及化工、环保技术领域，尤其是种管道混合器，它具有流体管，流体管的端设有与其相连通的支管作为稀释管，流体管中设有至少两块挡板，挡板朝着流体管的另端呈等间距交错排布；本发明结构简单、成本低廉，确保了两种气体在管道内的均匀混合，适用于大规模推广应用。
